Aliveness- is a not a minor difference in training either. In and of itself it is a major consideration for what the body can absorb, and redirect, what it can do in failure to turn the tables, what it can negate; either completely or partially, and what it can do to change the mindset and intent of the opponent and more importantly what it does to change your own mindset.

Everyone is familiar enough with my anti-ukemi rants so I won't go there again. Consider that the video showed two different waza being employed. The waza is consistent with any number of arts. How many think they would have been able to "catch" the opponent when that opponent was punching and kicking the crap out of you and trying to set you up in a calculated, experienced and planned methodology all his own?
The way to -get- there is to go there and train.
